Answer 1

Answer:

Speed of the cars are 22 kmph and 14 kmph.

Step-by-step explanation:

AB = 210 km

Let XO be the distance of 54 km.

therefore, Car A covered AX and Car B covered OB in 3 hrs.

Speed of Car A = x km/h

Speed of Car B = x-8 km/h

here, AX + OB = (210-54)km = 156km

then,

x = AX/3

x = AX/3x-8 = OB/3

x = AX/3x-8 = OB/3adding these, we get...

x = AX/3x-8 = OB/3adding these, we get...x+x+8 =AX/3 + OB/3

x = AX/3x-8 = OB/3adding these, we get...x+x+8 =AX/3 + OB/3=> 2x + 8 = 156/3

x = AX/3x-8 = OB/3adding these, we get...x+x+8 =AX/3 + OB/3=> 2x + 8 = 156/3=> 2x = 52 - 8

x = AX/3x-8 = OB/3adding these, we get...x+x+8 =AX/3 + OB/3=> 2x + 8 = 156/3=> 2x = 52 - 8 => x = 44/2

=> x = 22.

• speed of Car A = 22km/h
• speed of Car A = 22km/hspeed of Car B = 22-8 = 14km/h
